Hello Kylani and welcome to the Community! If you go to your assignment, you should see a box like the one below to allow you to submit an assignment.
When "Submit Assignment" is selected, another option like the one below should appear.
What options appear depend on how your instructor has the assignment set up. In this case, file uploads is allowed which is why there is a location to select a file to turn in. If this does not appear, you might contact your instructor. As I mentioned, the ability to attach a file is an option that must be selected by your instructor. At times I have found instructors at my own institution have forgotten to permit file uploads.
Do you see the file upload option in your assignment?
